STUIB-SHOE ATTACHMENT For; RUNNER-S or CORN Partisan-as on THE LIKE.

Application filed October 21, 1926. Serial No. 1433M.

This invention relates to a stub shoe attachment for the runner of a corn plant-er or the like, and it is an object of the inven tion to provide an attachment of this kind which serves to deflect stones or the like which may be in the path of the runner or shoe proper and which also operates to open up the ground in advance of the runner or shoe proper and more particularly to cut through sod or the like to produce a clearance for the runner proper.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved stub shoe attachment whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set' forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the ac companying drawing. wherein Figure l is a view in side elevation illustrating a stub shoe constructed in accordance with an embodiment of my invention in applied position;

Figure :2 is a View in top plan of the structure as illustrated in Figure 1.

As disclosed in the accompanying drawing, R denotes a runner or shoe of a conventional type employed in connection with a corn planter or the like.

Pivotally connected, as at 1, with the forward end portion of the runner or shoe R is the upper portion of a stub shoe S. This shoe S comprises an elongated plate or blade disposed in a vertical direction and has its lower forward marginal portion disposed on an outward curvature whereby is provided an entering point 2. The forward marginal portion of the shoe S immediately adj acent the point 2 and extending upwardly a predetermined distance is provided with a knife edge 3 which serves to cut through sod or the like to assure an efiective clean ance for the runner or shoe R.

Pivotally connected with the shoe S at substantially the central part thereof is an end portion of a rearwardly directed rod 4; which is slidably disposed through a laterally directed lug 5 carried by the upper rear portion of the runneror shoe R, the outward or forward movement of such rod being limited by the pins 6 selectively disposed through one of the openings 7 for contact with the lug 5.

Slidably mounted on the forward portion of the rod l is a sleeve or collar 8 held in desired position upon the rod by a set screw 9 or the like. Inter-posed between this sleeve or collar 8 and the lug 5 is an expansible member 10 herein disclosed as a coil spring encircling the rod 4 and which serves to normally maintain the shoe S at the limit of its forward movement.

By varying the position of the sleeve or collar 8 the tension of the expansible memher or spring 10 may be regulated or controlled as the requirements of practice may prefer.

In practice, the shoe S serves to deflect from the path of the runner or shoe It stones or the like which might otherwise interfere therewith and to provide requisite clearance for the runner or shoe It. In the event, however, the shoe S should come in contact with abnormal resistance odered by a stone, root or the like, the shoe S will swing upwardly against the tension of the member or spring 10 to clear such obstruction without injury to the shoerS or the associated part. When the shoe S is free of such obstructionthe member or spring 10 automatically returns the shoe to its normal working posltion.

From the foregoing description it is thought to be obvious that stub shoe attachment constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myselfito the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.

1. In combination with the runner of a planter, a vertically disposed shoe pivotally engaged with the forward portion of the planter, a rod pivotally engaged with the shoe and slidably engaged with the rear portion of the runner, and yieldable means coacting with the shoe and rod for normally maintaining the shoe in its working position.

2. In combination with the runner ot' a planter provided" with a laterally disposed projection at its rear portion, a vertically disposed shoe pivotally connected with the forward portion of the runner, a rod pivotally connected with the central portion of the shoe and slid-ably disposed through the 10 lateral projection of the runner, means carried by the rod and contacting with the projection to limit the forward swinging movement of the shoe, and an expansible spring coacting with the lateral projection of the runner and the forward portion of the rod for normally maintaining the shoe at the limit of its torward movement.

In testimony whereof I hereunto aliix my signature.

FRANK D. HABERMAN.
